(1-sin^2 theta) - (sin^2 theta)

Question

(1-sin^2 theta) * (sin^2 theta)

Answer 1

I see some algebra and trig, but no calculus

also, no question

Answer 2

Ooops, that's what I meant to write.

Can you simplify?

Answer 3

well, 1-sin^2 = cos^2, so you have

cos^2θ - sin^2θ = cos 2θ
cos^2θ * sin^2θ = 1/4 sin^2(2θ)
